D and I saw Next last night, and it's a good thing we didn't pay for it. (I used two AMC Gold passes I'd received as a thank-you for a special project at work.) The premise is intriguing--a man who can see exactly two minutes into his own future--but completely wasted on a total cheat of a story.
The credits claim that the film is based on the Philip K. Dick story "The Golden Man," but that's like saying Babe was based on Animal Farm. The short story is completely different, more ominous, thought-provoking, and just plain better.
That said, I do think there's the potential for a TV series based on Next--the final shot of the movie practically screams "THIS WAS A PILOT," and a good writing staff could take the premise and have a lot of fun with it. If Highlander and Stargate could redeem themselves on television, why not this piece of crap?
